Spinning oakum



UNITED STATES PATENT OFFICE.-

S. BALDVIN, OF ST. LOUIS, MISSOURI.

SPINNING OAKUM.

Specification of Letters Patent No. 19,011, `dated January 5, 1858.

To all whom it may concern:

Be it known that I, SMITH BALDWIN, of St. Louis, inthe county of St. Louis and State of Missouri, have invented a new and useful Machine for "Spinning Oakum; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making part of this specification, in which- Figure l, is a longitudinal vertical section of the machine. Fig. Q, is a plan of t-he saine. Fig. 3, is a transverse section of the same in the line m, a', of Fig. l, looking in the direction of the arrow shown near the said line.

Similar letters of reference indicate corresponding parts in the several figures.

This machine combines the processes of carding and spinning, and the picked oakum being supplied to it, is converted into a merchantable state for the use of calkers, &c., at one continuous operation.

T o enable others to make and use my machine, I will proceed to describe its construc tion and operation.

The portion of the machine seen at the right hand end of Figs. l and 2, is substantially like a common carding machine, except that a different device is employed to take the web of carded material from the doffer, and a device is added for the purpose of removing from the teeth of the doifer any tarry burs or knobs that may collect among the teeth, and that would interfere with the proper operation.

A, is the feed apron; and B, the platform on which the person stands to supply the picked material thereto.

C, C, are the feed rollers.

D, is the main cylinder.

E, F, G, are workers and strippers.

H, is a fancy cylinder; and I, is the dotfer.

J, J, are two series of revolving blades for taking the web from the doifer, attached to separate shafts arranged parallel with the doffer; the blades on one shaft being arranged midway between those on the other shaft, and the shafts rotating in opposite directions; so that the blades of the two shafts take the carded web between them, and pull it from the doifer, as shown in Fig. l where the oakum is shown in red color. The blades J, J, instead of having serrated edges like the combs commonly employed to take the carded material from the doffer of the common carding engines, have straight edges as shown in Fig. 2; as I find by experiment that the serrated comb edge 1s not adapted for removing the oakum without breaking the web, while the revolving straight-edged blades do it most effectually. The device for removing from the doffer the tarry burs or knobs, consists of a series of toothed or serrated blades a, a, attached to a shaft M, that rotates in the direction of the arrows, the teeth of the said blades operating upon the upper part of the dotfer to pick out the burs or knobs that remain among the teeth after the web has been removed from the dolfer.

O, is an endless apron, arranged in a nearly horizontal position, below the carding machinery, upon two rollers c, 01, and extending beyond both ends thereof, and having its upper surface moving in the direction of the arrow shown near N. N, is another endless apron running on two rollers 6, 6, placed under the combs J, J, and inclining outward from the machine toward the bottom, which is nearly close to the apron O. The outer surface of this apron N, has a descending motion and receives the web of carded material as it is delivered from the doffer by the revolving blades J, J, to convey it without breakage to the apron O, which, moving in the direction indicated, carries the web backward under the carding machinery toward the spinning or twisting devices at the left hand end of the machine. The arrangement and direction of the motion of this apron O, serve or are such as to receive all the short iibers which fall from the carding material, to be incorporated with the longer fibers in the spinning process, and hence to eect a considerable saving of otherwise worthless material.

P, P, are two stationary funnel-shaped conductors at the left-hand end of the apron O, which divide the web into two slivers, and condense it slightly as it leaves the said apron to be conveyed to the revolving roving tubes Q, Q, by which the required twist is imparted to it.

(l, is a pressure roller arranged above the roller c1, of the apron O, to effect a further condensation of the slivers as they leave the conductors P, P.

S, is a roller placed close above the apron O, at the edge of the stationary apron e, that is attached to the conductors P, P, said roller rotating in the direction of the ar-row shown near it, to prevent the web from passy ing under the said apron e, and to convey it to the said apron e, and conductors P, P.

f f, are gi'ooved drawing and condensing rollers, to draw the material slightly in its passage through the roving tubes and further condense it.

g, g, are two funnel shaped conductors to receive the rovings from the drawing rollers f, f, and lead them to the rollers L, h, upon which it is wound for the formation of banks of proper size for Vthe use of calkers or others; said conductors being attached to a sliding bar i, and having a lateral trans- .verse motion to cause the roving to be laid evenly upon the rollers h, 71 which are in tended to have proper mechanism applied to throw them out of the machine, to give place to an empty pair when a sufficient n purpose of taking the web of carded oakum in an unbroken sheet from the doffer.

2. The employment in combination with the said endless moving apron O, and the fr stationary apron e, belonging to the irst conductors 1), P,-of the roller S, operating v as and for the purpose specified.
